一种新型的宽带随机谱下疲劳寿命计算模型的建立与分析

Establishment and analysis of a new model for fatigue life prediction under broad band random loading

通过严密的数学推导和具体的数值分析，建立了一种新型的宽带随机载荷谱下疲劳寿命计算模型，数值计算表明。

By strictly mathematic derivation and particular analysis, a new model of fatigue life prediction under broad band random loading is established. The results of calculation show that the model has more suitable range and higher precision than other models.
